Definitions

  • the invention relates to a sanitary system with a flushing function, whereby the sanitary system can be, for example, a toilet or a urinal.
  • the sanitary system can be, for example, a toilet or a urinal.
  • a flushing system for the sanitary system and a method for operating the sanitary system are specified.
  • Sanitary systems in which rinsing water is supplied to a sink are known in a wide variety of designs.
  • pneumatically operating actuation devices are used for these sanitary systems, which have a transmitter bellows that can be compressed using an actuation button, the gas volume displaced when the actuation button is pressed is fed to a slave bellows.
  • the expansion of the receiver bellows opens a drain valve of a flushing water tank, which can be closed or closes again either as required or after the flushing water has drained away.
  • Examples of such pneumatically operating actuation devices are in DE 298 20 855 U1 , DE 10 2008 027 255 A1 , DE 100 61 615 A1 , DE 37 29 569 A1 and EP 1 719 846 A2 described.
  • While many of the known actuating devices are generally used to trigger a movement of the valve body of a cistern drain valve from the valve seat and work pneumatically for this purpose, particularly in publicly accessible sanitary facilities, for example to increase hygiene and / or to minimize the effects of vandalism
  • electrical actuation devices such as infrared sensors
  • battery solutions are used to supply electrical energy, in particular in order to be able to retrofit the actuating devices into existing sanitary facilities that usually do not have a power connection.
  • a sanitary system with a flushing function contributes to this, having a flushing system with a cistern for storing flushing water, a water supply line for supplying water into the cistern and a drain valve for releasing flushing water from the cistern as required, the flushing system having at least one connected to the water supply line, has an electrically controllable (solenoid) valve that is set up in this way and is arranged so that water can be made available via the water supply line in order to open the drain valve.
  • the electrically controllable valve is preferably an electrically controllable solenoid valve.
  • the solution described here can advantageously contribute to the fact that electrical energy no longer has to be used to overcome the lifting force. Rather, the water pressure from the water supply line or from a supply line connected to the water supply line can be used here to lift out the drain valve (in particular via a bellows), controlled via the (solenoid) valve.
  • the electrically controllable (magnetic) valve can, for example, be set up in such a way that water can be made available via the water supply line or introduced into the cistern for one or more (pre-)definable opening times and/or with one or more (pre-)definable degrees of opening is. This can advantageously contribute to setting different flush quantities.
  • the opening period and/or the degree of opening are defined in particular in such a way that they are sufficient for lifting a valve body out of a drain valve seat. “Lifting” here is understood to mean, in particular, lifting and/or distancing from one another, which is (just) sufficient to enable a flushing flow through the drain valve.
  • the flushing system has a filling valve that can be operated independently of the (solenoid) valve.
  • the filling valve can be set up and arranged in such a way that the cistern can be automatically filled via the water supply line until a (pre-)definable flushing water supply quantity is reached.
  • the (solenoid) valve could contribute to filling the cistern.
  • the (solenoid) valve would preferably be used Execution of at least two different functionalities, namely the filling function and the drain valve opening function (in the foreground here) is provided and set up.
  • the flushing system has a conversion unit which is set up and arranged in such a way that water pressure that can be released via the (magnetic) valve can be converted into air pressure for opening the drain valve.
  • the conversion unit can, for example, use a force resulting from the water pressure to generate the air pressure.
  • the conversion unit can work rotationally or translationally or carry out corresponding movements.
  • the conversion unit can, for example, have at least one cylinder device which has a cylinder (piston) that can be engaged using water pressure.
  • the cylinder (piston) can move into a chamber in which there is air.
  • the cylinder (piston) can therefore help to compress this air and thus build up air pressure.
  • the flushing system can, for example, have an air supply line which connects the conversion unit to a bellows assigned to the drain valve. Air directed into the bellows can be used to lift it. For example, via a mechanical coupling, the bellows can contribute to opening the drain valve, in particular to lifting a valve body mechanically connected to the bellows out of the drain valve seat.
  • the electrically controllable (solenoid) valve is set up and arranged in such a way that at least a definable amount of water can be discharged or introduced (directly) into the cistern in order to to open the drain valve.
  • a briefly increased amount of water in the cistern can in principle also advantageously contribute to lifting the valve body out of the drain valve seat.
  • the drain valve can be set up in such a way, in particular a body of the drain valve, can be shaped in such a way that at least an upper part of the drain valve floats when the (pre-)definable flushing water supply quantity is exceeded and can thus open the drain valve.
  • the electrically controllable (magnetic) valve can be set up and arranged so that at least a definable amount of water can be discharged or introduced (directly) into the drain valve arranged in the cistern in order to open the drain valve.
  • the flushing system has a pressure reducer which is arranged upstream or downstream of the (solenoid) valve in order to reduce the water pressure from the water supply line.
  • a pressure reducer which is arranged upstream or downstream of the (solenoid) valve in order to reduce the water pressure from the water supply line.
  • the flushing system has a mechanical lifting system with one or more cylinders that can be actuated by water pressure and can be controlled via the at least one (solenoid) valve in order to open the drain valve.
  • a flushing system for a sanitary facility described here is specified, with a cistern for storing flushing water, a water supply line for supplying water into the cistern and a drain valve for releasing flushing water from the cistern as needed, and with at least one with the Water supply line connected, electrically controllable (solenoid) valve, which is set up and arranged so that water can be made available via the water supply line in order to open the drain valve.
  • steps a), b) and c) is exemplary and can, for example, be carried out at least once in the specified order to carry out the method. Alternatively or cumulatively, steps a), b) and c) can be carried out at least partially in parallel or simultaneously.
  • Fig. 1 shows schematically an example of a sanitary system 1 with a flushing function, having a flushing system 2 with a cistern 3 for storing flushing water, a water supply line 4 for supplying water into the cistern 3 and a drain valve 5 for releasing flushing water from the cistern 3 as required, where the flushing system 2 has at least one electrically controllable valve 6 connected to the water supply line 4, which is set up and arranged so that water can be made available via the water supply line 4 in order to open the drain valve 5.
  • valve 6 here is an electrically controllable solenoid valve 6.
  • the sanitary system 1 here has an actuating device 15 as an example.
  • the actuation device 15 is used to manually actuate the flushing function by a user.
  • the actuating device 15 can be, for example a non-contact actuating device 15, which can include, for example, an infrared sensor and / or an optical sensor.
  • the actuating device 15 can output an electrical signal to control the solenoid valve 6.
  • the sanitary system 1 here also has, for example, a toilet bowl 16 into which the flushing water can be discharged from the drain valve 5.
  • the flushing system 2 can, for example, have a filling valve 7 that can be operated independently of the solenoid valve 6 and is set up and arranged in such a way that the cistern 3 can be filled automatically via the water supply line 4 until a definable flushing water supply quantity is reached.
  • the flushing system 2 can have a conversion unit 8, which is set up and arranged in such a way that the water pressure that can be released via the solenoid valve 6 can be converted into air pressure for opening the drain valve 5.
  • the conversion unit 8 here has, for example, at least one cylinder device 9, which has a cylinder that can be engaged using water pressure.
  • the flushing system 2 has an air supply line 10, which connects the conversion unit 8 with a bellows 11 assigned to the drain valve 5.
  • the air provided by the conversion unit 8 can be used, for example, to lift the bellows 11 and thus lift the valve body of the drain valve 5 out of the drain valve seat.
  • the bellows 11 and the valve body of the drain valve 5 can be mechanically connected to one another.
  • Fig. 2 shows schematically another example of a sanitary system 1 described here with a flushing function.
  • the reference numbers are used consistently so that reference can be made to the previous explanations.
  • Fig. 2 is shown as an example that the electrically controllable solenoid valve 6 can be set up and arranged so that at least a definable amount of water can be discharged (directly) into the cistern 3 in order to open the drain valve 5.

  • a single solenoid valve 6 and, for example, two cylinders 14 are present.
  • the (lower) cylinder 14, which can be directly controlled by means of the solenoid valve 6, has, for example, a larger water pressure application area than the other (counter) cylinder 14.
  • the cistern 3 can be filled until a defined amount of flushing water is reached.
  • An electrical signal can be triggered via an actuating device 15 of the sanitary system 1.
  • the electrically controllable solenoid valve 6 can be opened depending on the electrical signal in order to add additional quantity of flushing water via the water supply line 4
